A new program offered by MEPhI scientists on beam momentum scan with Pb+Pb collisions [1] at NA61/SHINE has been endorsed at the 120th meeting of SPS and PS experiments Committee (SPSC) which was held in CERN this January.
The program was presented by Associate Professor of the Department №67 Ilya Selyuzhenkov [2] at the 119th Meeting of the SPSC Committee in CERN [3]. He is the MEPhI head of the research of collective flows in heavy-ion collisions in NA61/SHINE experiment responsible for preparation of this part of the program.
The analysis of data [4], of the test of nuclei Pb beams with the energy of 30 gigaelectronvolt carried out in CERN in November, 2015, has played a key role in new program endorsement. This analysis has shown its possibility of usage for measuring of collective flows of front hadron calorimeter which measures energy distribution of projectile nuclei fragments (PSD). A new central module which was used in the test for PSD had been created last year in MEPhI under the supervision of Department №67 Associate Professor, PhD Arkadiy Taranenko together with a group from INR RAS supervised by leading research worker Fedor Guber.
The first physical data for NA61/SHINE for Pb nuclei is expected in the end of 2016. In 2016 there are going to be modernization works on the electronics of hadron calorimeter PSD, data analysis and joint publishing.
Students and post-graduate students take part in the NA61/SHINE experiment. Alexander Zaitsev and Svetlana Vdovkina were among the first to test in November, 2015.
Training of specialists with experience in large international experiments is very important for future tests like hard-ion collision tests at NICA accelerator complex in Dubna.
